YARN-PRINTING IVIACHlNE.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed September 23, 1904. Serial No. 225.645.

[0 all whom it may concern.-

Be it known that I, WAYNE K. HAWK, a citizen of the United States, and a resident of Falls of Schuylkilhin the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Yarn-Printing Machine, of which the following is a full, clear, and exact description.

The invention relates to machines for producing printed yarns such as are used by carpetmanufacturers in making tapestry and velvet carpets, rugs, and like fabrics.

The object of the invention is to provide a new and improved yarn-printing machine-arranged to permit printing yarns of any desired length, and more especially such as are required in the weaving of large rugs known as art-squares, the arrangement being such that the same printing-drum will answer in printing long or short yarn.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement. Fig. 2 is an end view of the printingdrum and adjacent parts, and Fig. 3 is an end view of the idler-drum.

The printing-drum A, of any approved construction, is mounted on the main frame B, and over a portion of the said drum extends a blanket C, winding up at one end on a roller D and unwinding at its other end from a roller E, both rollers being jonrnaled in the main frame B and driven from the shaft A of the printing-d rum A by suitable friction-gears F and F, respectively. The yarn Gr extends around the printing-drum at the portion covered by the blanket C, and the yarn also passes around an idler-drum H, having its shaft H journaled in a stand 1, preferably mounted on wheels I to allow of moving the said stand I and the idler-drum H nearer to or farther from the n'inting-drum A, according to the length of the yarn to be treated. The idler-drum H is positively driven from the shaft A of the printing-drum A by the use of a suitable positive gearing J proportioned to cause the idlerdrum H to rotate with the same surface speed asthe printing-drum A. Theaxisof theidlerdrum H is located somewhat higher from the supporting-floor than the axis of the printingdrum A to hold the yarn G in engagen'ient with the bottom of the printing-drum somewhat beyond the central point thereof to allow proper contact of a printing-roller K with the yarn.

The printing-roller K is mounted on the usual traverse-carriage L, and the guide N for guiding the yarn onto the printing-drum A is of the usual construction, so that further description of the traverse-carriage L, the printing-roller K and its color-box, and the guide N is not deemed necessary.

The front bearings for the drums A and H are removable to allow of conveniently removing the yarn from the drums after the same is printed.

For filling the machine with the yarn the four or more ends of the yarn are drawn over the top of the printing-drum A and then over the idler-drum H and back underneath both drums, after which the ends are tied together. The machine is now started by rotating the printing-drum A, thereby causing a simultaneous rotating of the rollers .l) and E and the idler-drum H to cause winding of the balance of the yarn on the drums A and H. While the drums A and Hare being filled, the blanket C is wound up on eitherblanket-roller D or E, and after the drums A and H are filled the outer end of the blanket is drawn onto the peripheral face of the printingdrum A at a point where the yarn meets the printing drum A. A further rotation of the printingdrumA now causes the blanket to pass around the drum beneath the yarn, the latter holding the blanket with snflicient force in contact with the peripheral face of the printing-drum for the blanket (.3 to travel with the printing drum. The end of the blanket after leaving the printing-drum A is then wound on the other blanket-roller E or D. Thus if the printing-drum A rotates in the direction of the arrow a the blanket is first wound up on the rollerD, then passed to the printing-drum at the bottom thereof, and then around the printing-drum A underneath the yarn G to the top of the ninting-drum, and finally wound up on the roller E. In case the printing-drum revolves in the reverse direction of the arrow a the blanket is first wound up on the roller E, then passed to the top of the printing-drum,

around the same underneath the yarn to the bottom of the printing-drum, to be finally wound up on the roller D. After the yarn is in position on the drums then the printing is done in the same manner as heretofore practiced, with the exception that on an ordinary drum each straw of the printed surface is represented by a tooth on a ratchet-wheel extending around the end of the drum just inside of the lagging. In the present case use is made of an indicating device 0 in the form of a clock having two hands, (see Fig. 2,)one to represent units and the other tens, the said indicating device being used in place of the ordinary index. What would be the minutehand on a time-clock would be figured from l to 10 for the units, the one half representing the tens and the other units. By this arrangement it is possible to obtain any length of printed yarn desired. After the yarn is printed it is removed from the drums in practically the same manner as from the ordinary drumthat is, the front bearings for the shafts of the drums A and H are swung downward, and then a portion of the peripheryof the face of the drumA is collapsed to slacken the yarn, so that it can be removed from the drums, after which the blanket is unwound from the rollers D and E and removed for the purpose of washing, &c.

By the arrangement described it is not necessary to use an exceedingly large drum A, as by employing the auxiliary or idler drum H and placing the same a distance from the printing-drum A any desired length of yarn can be obtained. Thus, for instance, if the printing-drum A is eight feet in diameter and it is desired to print yarn for a nine-foot rug it is necessary to move the stand I and the idlerdrum H nearer to the printing-drum A than when it is desired to print for a'rug twelve or fourteen feet, as then the stand I and its drum H are moved farther away from the printing-drum A; but in all cases the stand I is held in such position relative to the frame B that the shafts A and H are parallel one to the other.

The shaft J of the gearing J is of sufficient length to allow moving the stand I and its drum H nearer to or farther from the printing-drum A without disconnecting the gearlng.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent 1. A yarn-printing machine comprising a printing-drum on which the yarn is printed,

an idler-drum over which passes the yarn, a blanket passing over the said printing-drum, and unwinding and winding-up rollers for the said blanket, arranged between the said printing-drum and the said idler-drum.

2. A yarn-printing machine comprising a printing-drum on which the yarn is printed, an idler-drum over which passes the yarn, a movable stand in which the said idler-drum is journaled, a blanket passing over the said printing-drum, and unwinding and windingup rollers for the said blanket, arranged between the said printing-drum and the said idler-drum.

3. A yarn-printing machine comprising a printing-drum on which the yarn is printed, an idler-drum over which passes the yarn, a movable stand in which the said idler-drum is journaled, a blanket passing over the said printing-drum, unwinding and winding-up rollers for the said blanket, arranged between the said printing-drum and the said idlerdrum, and means for driving the said idlerdrum and the said unwinding and winding-up rollers in unison with the said printing-drum.

I. A yarn-printing machine comprising a printing-drum on which the yarn is printed, an idler-drum over which passes the yarn, means for driving the idler-drum at the same surface speed as the printing-drum, a blanket passing over the printing-drum, and rollers for winding up and unwinding the said blanket, driven from the said printing-drum.

5. A yarn-printing machine comprising a printing-drum on which the yarn is printed, an idler-drum over which passes the yarn, a frame 'in which the said printing-drum is journaled, and a movable stand in which the said idler-drum is journaled, the front bearings for the said drums being removable.

6. A yarn-printing machine comprising a printing-drum on which the yarn is printed, an idler-drum over which passes the yarn, a blanket passing over the said printing-drum, unwinding and winding-up rollers for the said blanket, and means for driving the said idlerdrum and the said unwinding and Winding-up rollers in unison with and from the said printing-drum.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
